CBN(Cubic Boron Nitride /立方氮化硼)烧结体如下表所示，硬度仅次于钻石，约为硬质合金的3倍, 是具有更高耐热性、热传导性的刀具材料。但是，同时也有强度和韧性低，易崩刃的缺点。在刀具刃尖阻力较大的粗加工中，容易出现崩刃的情况，所以CBN刀具不适合用于粗加工。但在切削阻力小的精加工中, 由于CBN优异的硬度和耐热性，可降低刀具磨损，刀具使用寿命超长，尤其适用于高硬度材料的加工。 CBN(Cubic Boron Nitride) sintered alloy is 3 times harder than Tungsten carbide, second hardest material next to diamond, moreover strong heat-resistant and high thermal conductivity. However less tough characteristic of CBN often causes chipping of tool edge easily. Accordingly, CBN is recommended for finishing of hard materials with less cutting load on the tool edge, which guarantees extra long tool life.

PCD是使用微小人造钻石颗粒和结合材料(Co等)的粉末，通过超高压、高温烧结成的钻石，也称为多 晶钻石。与单晶钻石一样，硬度高、耐磨性优异。但因不耐热而用途受限。主要运用于脆性材料的加工中。 PCD consists micron-size artificial diamond powders sintered with binding materials such as Co and etc. at high pressure and temperature. PCD is as hard as Monocrystalline Diamond featuring strong wear-resistance. However the use is limited as being fragile against heat .It is mostly used for the machining of brittle materials.
